Abstract

The filling machine has a rotary tank containing the liquid, an annular channel surrounding the tank and containing gas having a lower pressure than the gas in the tank but higher than the atmospheric pressure, a filling unit adapted for sealing the container to be filled and including a filling pipe communicating with the interior of the tank and projecting into the container to be filled, a pressure control space communicating with the interior of the container around the filling pipe and connectable via a first control valve to the outer atmosphere, and further connectable via a second control valve to the annular channel, the second control valve being opened mechanically in response to the angular position of the rotary liquid tank and in addition being controlled during its open position by a separate timing device that closes the second valve if the mechanical control exceeds a predetermined time.
